Core FIR[60] is a side effect of the work around for the CI Vector Load
issue in DD2.1. Usually this gets delivered as HMI with HMER[17] where
Linux already ignores it. But it looks like in some cases we may happen
to see CORE_FIR[60] while we are already in Malfunction Alert HMI
(HMER[0]) due to other reasons e.g. CAPI recovery or NPU xstop. If that
happens then just ignore it instead of crashing kernel as not recoverable.
